Free Ohio CDL Practice Test Questions

by Joshua on July 03, 2014

It is important to practice your Commercial Driver’s License exams before plunging into the exam at your local Ohio Bureau of Motor Vehicles. Prior to obtaining your CDL in Ohio, you will need to take one or more written examinations called Knowledge Tests. These Knowledge Tests are mandatory for you to take the hands-on skills test.

Why Take CDL Practice Tests?

You may want to take a free practice Commercial Driver’s License test for many reasons. After reading all of the information in your Ohio Bureau of Motor Vehicles Driver’s Handbook, you may be feeling overwhelmed. There is so much information in these handbooks that it becomes hard to tell what to expect on the examinations. Not to mention that you may have to take more than one test. It is no fun to have to take an examination over and over again and also pay the appropriate fees. With a “practice test” , you can answer the questions and go back to see which ones you did not answer correctly. It gives you an opportunity to get back into test taking mode, which you may have not had to do since high school. Tests can be stressful and nerve racking. Practicing tests can calm down your test taking jitters, especially when you know what to be expecting studying the handbook and taking practice tests are probably the most important things you can do to ensure that you will pass your Commercial Driver’s License Test with passing colors!

Written Knowledge Tests

The Knowledge Tests can be one or more tests that you must take depending on what type of vehicle you will be driving and what type of cargo you may be hauling. The subcategories of the written Knowledge Tests are:

  • The General Knowledge Test
  • Use of Vehicle Air Brakes
  • Combination Vehicles
  • Driving Doubles/Triples
  • Hauling Hazardous Materials
  • Passenger Busses
  • School Busses
  • Pre-Trip Safety Inspection
  • Tanker Trucks

The General Knowledge test is required for any commercial driver. In order to haul hazardous materials you will need to pass a background check from the Transportation Safety Administration. You can get more information here

Free Practice Test Resources

There are many resources which offer free practice testing in order to help you pass your Commercial Driver’s License examinations. However, they are not all created equal. Many of these websites are out of date or do not have accurate questions and answers. Be sure to use a resource that has the most up to date information as laws and regulations are always changing.

There are also resource practice tests which must be paid for. These tests tend to be more up to date and reliable as they are for profit. Make sure to thoroughly check out your source of practice test before spending time on them. You can always email the webmaster or owner of the website and ask them if their information is up to date. You can also get plenty of resources at your local commercial vehicle driving school.
